PROBLEM TO BE SOLVED: To provide a game machine designed to give benefit to a player that can raise the player's expectation by notifying the player of information on giving benefit before pattern fixation. SOLUTION: A pachinko machine 10 once displays a temporary jackpot arrangement of patterns in picture display lines 110 to 150 on a screen 20a to show giving a jackpot game (primary benefit). The pattern display lines 110 to 150 next make three synchronous repetitions of alternate high-speed changing and temporary stopping, before displaying a fixed jackpot arrangement of pictures when fourthly stopped. The ratio or proportion of probability- increasing pictures ensuring another probability-increased game to the other patterns in the synchronously changed pattern arrangements displayed at the temporary stops is determinative of the probability that the fixed jackpot arrangement of patterns will be displayed in favor of such a probability- increased game (secondary benefit). |
